Gut for tennis racket and the like and method of making same

Abstract

Improved gut for use on rackets for tennis, badminton, and the like, comprising a gut body and a coating film on the gut body, the film being obtained by drying a liquid formed by dispersing minute particles of ethylene tetrafluoride resin either in a solvent or a molten resin.

I claim: 
     
       1. Gut for a tennis racket or the like comprising a gut body and a coating film on the surface of said gut body, said film being a dried liquid containing minute particles of ethylene tetrafluoride resin.   
     
     
       2. Gut as defined in claim 1 wherein said particles are of a diameter in the order of 0.1 to 10 microns. 
     
     
       3. Gut as defined in claim 1 wherein said particles are of a diameter in the order of 0.3 microns. 
     
     
       4. Gut as defined in claim 1 wherein said dried liquid was a solution of said ethylene tetrafluoride particles in a solvent. 
     
     
       5. Gut as defined in claim 1 wherein said dried liquid was a mixture of said ethylene tetrafluoride particles in a molten resin. 
     
     
       6. A method of forming a gut for a tennis racket or the like comprising applying to a gut body a coating film of minute particles of ethylene tetrafluoride resin dispersed in a liquid, and drying the liquid. 
     
     
       7. A method as defined in claim 6 including dispersing the particles in a solvent prior to applying, and permitting the solvent to evaporate after applying. 
     
     
       8. A method as defined in claim 6 including dispersing the particles in a molten resin prior to applying, and permitting the melt to cool and solidify after applying. 
     
     
       9. A method as defined in claim 6 wherein the particles are of a diameter in the order of 0.1 to 10 microns. 
     
     
       10. A method as defined in claim 6 wherein the particles are of a diameter in the order of 0.3 microns.
